This got us thinking.... is there a way to do these when we're too lazy to push things around a frying pan?
Slice the plantain into quarter-inch pieces. Sprinkle with salt if desired. Cook on a well-greased waffle iron until soft all the way through, like you would a baked potato.
Indeed there is! Furthermore, since these are getting heat pressed onto them on both sides, it's actually faster than doing them in a frying pan! And these are so, so good.
